1999 Gekko, with 5.7 vortec pcm engine. Took out other day going wide open and then got louder exhaust noise and started to over heat. Did not see anywater leaking from manifolds but soon as it go loud noticed the water temp climbing. New to inboards and would like to know where to start looking. Advice from many water pump, why did it get loud first? Should I check collapsed muffler, manifold? It didn't lose any power when it got loud, just over heated and fast! Will look further this wkend, just need a starting place. Don't want to go to deal if I don't have to.

It got louder because it sounds like there wasn't any water flowing through the exhaust system. Since it happened over a short period of time, I'd start by checking to see if you sucked something up into the raw water strainer. If clear then go to the raw water pump and see if the impeller is ok. You haven't been running this boat dry even for short brief times have you? Without water, it doesn't take much to burn up a impeller!

Gekko , is that not a lizard?????
Sounds like an impeller for raw water in,extra water is dumped into the water manifolds after the coolant loop.No water /extra loud/ water helps to cool and dampen the exhaust note.......

Some live and learn, some just keep repeating and expecting different results.........
Raw water cools the motor and also lubes the impeller, hope ya find all the pieces to the impeller puzzle........

I could be off here, but do gekkos even have strainers? No one used to back in the day except CC.

I think we may still be living in "the day". MC still doesnt install a strainer as standard equipment.

hey i would now check your impeller, take the water pump off and open it up, we had this problem and the impeller got melted and was hooped, so check that cause if there isnt enough impeller left it wont suck enough water and overheat and will be loud

Brandon,
I hope that whoever is in you family that's in charge of the boat has now too learned that you don't run a boat dry!

Yep! But one smart thing Indmar does do is they put their transmission cooler after the raw water pump. You can always find the impeller pieces when it lets go as they accululate in the cooler and not in the thermostat housing.
Only one thing can beat cubic inches! And that is cubic Dollars!

took the front cover off the water pump and the impeller looks fine...all the rubber is there, I'll admit that it got hot when I set the carb running it dry, would it still look fine but not pump properly, the rubber getting too soft? Tried to take it out of its housing, do you need a special puller. Also took off the raw water intake at the pump and was able to blow threw it no problem. Going to hook up to garden hose this wkend and start seeing it it pumps. Took off thermostat housing...thermostat looks rusty, it also is one piece and couldn't get it out of the housing. My thinking is that even with a fbar thermostat it should still pump enough water not to give loud exhaust. Looked in the exhaust last night also, both side seem to be the same. When manifods pack it in do they cause a heating problem or just leak? Have no dealers in this area to even talk to....

Sounds like a coolant flow issue.

Exhaust Manifolds:
Usually the manifolds will only warp or crack causing an internal (into engine) or external (into bilge) water leak. This type of exhaust manifold leak does not cause an overheating condition.

Also check your raw water intake line at the inline trans cooler, on some boats this is the first strainer. I'd want to look at it first as I want to know why my boat is running hot, but you can back flush the trans cooler from the raw water pump with a garden hose.

even though the water impeller has all the rubber showing I would like to pull it out and see just how soft the rubber is. Do I need a puller to get it off the shaft? Also, is the thermostat one piece, not like a car stat! Looks like it is seized into the housing.

Don't use the garden hose to check flow through the pump. The pressure from the hose will give you a false indication of water flow. Stick the suction hose on the RWP into a bucket of water so it has to suck up the water. You shouldn't need a puller to get the impeller out. The rubber won't get soft but rather hard after overheating. Get a new impeller. You should not be able to blow through the pump.

The garden hose will fool you. I had my pump backwards and it worked fine at the house with the garden hose. Good thing that I learned from the last screwp up is that always touch the back of the pump after putting the boat on the water and starting it up and make sure is cold.

Put a new impeller in, the one I took out looked perfect, however, the rubber had spun on the brass. Took the boat out and it would run anywhere from 160 up to 185. Should the temp stay exactly at say 170 or if a slight fluctuation normal? Wide open 4900rpm quiet exhaust!

Sounds like you found the problem! Happy boating. The temp fluctuation is normal.
